If additional tests required eg. CSF oligoclonal bands, a minimum of 1.0 ml is required.

Collect CSF into three separate, sterile, screw-capped tubes provided (labelled 1,2 & 3)

Tube 1 is for Biochemistry (for Protein and Glucose) 0.5ml (10 drops) required 

Tube 2 for Cytology 1.0ml (20 drops)  and/or Flow Cytometry (6ml)

For Flow Cytometry a minimum of 6ml is required  in Tube 2

For Flow Cytometry and Cytology a minimum of 7ml is required in Tube 2     

Tube 3 for Microbiology upto 10ml (Full tube)

If querying CJD the laboratory requires a 4th unopened tube containing at least 1ml of non-bloodstained CSF.

Xanthochromia investigation requires a 4th tube containing 1ml of CSF .

Notes:

Glucose and Protein are determined routinely

Glucose result should be compared with plasma glucose taken at the same time

Results on blood-stained CSF are unreliable

Testing for oligoclonal bands performed on request (serum must also be provided) .

Daily
Result Turnaround Time:
